Answer 1

创建对您的 ImageView 的引用并将其从 super View 中删除，并使用您的图标图像创建新的 ImageView 并将其添加到您的 TextView 中。如果您在 TextView 的顶部添加 ImageView ，它将在 TextView 中隐藏您的文本。

添加 TextView

在您的 .m 文件中

> UITextView *textView; UIImageView *testImageView;
> 
> -(void)addMyTextViewWithImage{
>     self.textView = [[UITextView alloc]initWithFrame:CGRectMake(50.0f, 50.0f, 200.0f, 200.0f)];
>     self.textView.inputView = [[UIView alloc]initWithFrame:CGRectMake(0.0f, 0.0f, 0.0f, 0.0f)];
>     self.textView.backgroundColor = [UIColor blackColor];
>     self.textView.textColor = [UIColor whiteColor];
>     self.textView.font = [UIFont fontWithName:@"HelveticaNeue-UltraLight" size:30];
>     self.textView.text = @"Lorem ipsum dolor sit er elit lamet, consectetaur cillium adipisicing pecu, sed do eiusmo to factor tum
> poen legum odioque civiuda.";
>     self.testImageView = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"yourimage.png"]];
>     [self.testImageView setFrame:CGRectMake(10, 10, 150, 30)];
>     [self.textView addSubview:self.testImageView];
>     [self.view addSubview:self.textView]; }
> 
> -(void)removeAndUpdateWithIconImage{
>        //Remove my imageview from text view
>       [self.testImageView removeFromSuperView];
>       
>       //Add the imageview with desire frame and icon image
>           self.testImageView = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"icon.png"]];
>           [self.testImageView setFrame:CGRectMake(10, 10, 150, 30)];
>          [self.textView addSubview:self.testImageView];
>
